Re: [PHP] [? BUG ?] weird thing;downloading from a php script stops at exactly 2.000.000 bytes
Hi,
There is not a big speed difference between the two.
The only thing is that it was frustrating to find out the limitations
on readfile.
I used it before with large files and it was ok; only to find out now
that on 5.0.4 it doesn't work as it used to.
As php manual states readfile should be the way to spit a file out
the wire.
btw:
$fp = fopen('somefile');
fpassthru($fp);
is also stopping at 2.000.000 bytes, which definetely drives me
to think there is a bug somewhere.

[PHP] Howto implement atomical actions
Hi all I am developing a web interface to patch a program. The user uploads the patch and after uncompressing and verification of signature, the update should take place. However I do not want users to be able to start an update and then abort the process by stopping to load the page. I imagine that by calling a program externally from php that it would be possible but there are limitations because of the distribution. The systems are installed on php+mysql+apache servers but no shell access is granted. I greatly appreciate help in this matter.

Re: [PHP] using require
Hi, this depends on which connection-function you've used. If you've decided to use pg_pconnect(), there is just one connection. If you use pg_connect, everytime a new connection is established (and after finishing the script, it's closed though) HTH Christian hi all, i have my web site working something like this: in every php script i have require(auth.php). this auth.php has my connection to my postgresql server and database along with some other stuff i need for the user to be authenticated to my web site. when i log on, this auth.php connects to the dbserver and checks if my username and password are stored and then i go to a home page. my connection is stored in $dbh. what happens when i start moving through all these web pages (php scripts), each requires auth.php, with respect to the connection? is a new connection established for every web page i go into that uses my $dbh for querying purposes or is it the same connection i originally made when i first logged into the web site? any info will be highly appreciated!! thanx. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For example, upload to a temporary directory, and, as your last PHP step, use http://php.net/rename to move the uploaded file to a "to_be_installed" directory. Then you can have cron job 2 minutes that installs anything it finds in that directory. At that point, nothing the user can do can interfere. That wouldn't necessarily make the operation atomic... What makes a "patch" atomic?... You'd be looking at something like subversion for that, I should think...

Assuming there is not function in myfunction.php, and it's just raw
PHP/HTML code...
This is slower, UNLESS you have something like Zend Cache (or whatever
it's called now) *AND* that is configured to not check filemtime on every
hit...
At that point, this could probably be faster.

The overhead for a function is not zero, but it also depends a little bit
on what arguments you are passing to the function.
Have you actually tried it yet, either way?
Cuz I suspect you are worrying over a lot of nothing...
Try it the cleanest most maintainable way.
Worry about performance after it fails.
"Look before you leap" is good advice, but not when don't have enough data
to "look" -- Find out if it's "too slow" then make an informed decision.
Especially for 6 lines of code.
5,000 iterations isn't gonna kill you, I'll bet.

You probably have a very clear user-interaction-path into and out of SSL anyway, so you'd only be changing a couple lines of code, in a well-designed application. Essentially, it's probably best to think of your HTTP and HTTPS as two totally different servers, with nothing in common, even when, in fact, they are the same server with the same files in the same exact hard drive and all that.

[Plus I'm not on the internals list.] Re-direct followups off-list or back to -internals or ... I don't think ifsetor is going to encourage newbies to check variables before use. In fact, I think it's just going to confuse newbies with one more extra way to do the same thing. Only turning E_ALL on by default (which I asked for in PHP 4.0 and PHP 5.0 and will ask again for PHP 6.0 and 7.0 and 8.0 ...) will actually educate newbies that they are doing something fundamentaly "wrong" in their Programming to use variables they haven't initialized. Spare the rod, spoil the child. Spare the E_NOTICE, spoil the newbie. There's currently NOTHING other than 10,000 pages of docs to tell a newbie they NEED to check vars. The quickie examples everybody rattles off don't check vars. The MANUAL doesn't even consistently use good programming practices in its examples -- though it gets better over time, mostly. Then people want to "simplify" the examples down to just the function/feature in question, and we go back to Bad Code. ifsetor doesn't really seem to add much value to me. $foo $: $default; $foo = ifsetor($default); $foo = isset($foo) ? $foo : $default; What? 15 to 20 characters, depending on the ifsetor syntax? I'll pass. I don't think ifsetor adds enough value to the language to be worth the confusion of having a second way to do the same thing in ~20 more characters, personally. [shrug] If it gets added, I'll probably never even bother to use it. I've been typing the isset() ? : construct for so many years, that I'm not gonna switch for the sake of a few less keystrokes. Sorry. I certainly don't want to be the one answering the 10,000 emails to this list: Which is better? isset() ? : or ifsetor? Which one is faster? Why are there two ways to do this? What's this ifsetor thing? / What's this isset() ? : thing? And then the arguments between the experts (self included) over which one is "better" and why. Cuz I'll tell you right here, right now, that's one consequence of this proposed change. 10,000 more emails to php-general in the next year or two, just about 'ifsetor'.
